Hi,  I have two source types CardMember_cycle_data (with card member cycle date info) and CardMember_Demographic_data (with card member demographic info).  Both files have more than 3-4 million records each.  (all dates are in MM/DD/YYYY format)  CardMember_cycle_data  CM_id   Cycle_Date  CM1       05/01/2023  CM1       06/01/2023  CM2       04/03/2023  CM2       05/03/2023  CM2       06/03/2023  --------------------------  CardMember_Demographic_data  CM_id Transaction_Dt   Prod_Code  CM1     01/02/2020        CR  CM1     05/28/2023        XX  CM1     06/07/2023        AB  CM2     04/14/2023        YY  CM2     06/01/2023        CD  My need is -  For each Card Member present in CardMember_cycle_data I need to get the latest Prod_Code as of LATEST Cycle_Date.  Hence the output will be:  CardMember     Latest_Cycle_Date     Prod_Code  CM1                       06/01/2023                  XX  CM2                       06/03/2023                  CD
